my door closer closes way too fast

[jmjoseph]

Hello,

I have a door that has a Ryobi door closer on it. The door closer has worked good up to 3 months ago. Now everytime I open my door the door closer goes much faster and usually ends up slamming into the door frame.

I have played around with the spring adjusting nut but it still goes very fast at the beginning and sometimes it will stop about 6 inches from the frame and then slowly (very slowly) close.

Has anyone else had this problem or know how to fix it.

Thanks

Hello JMJoseph:
You are on the right track, now just make small adjustments between the two extremes until you get the desired effect; say, maybe a quarter turn at a time.
